Abstract
To improve ablation resistance of PIP-C/SiC composites, ZrCSiC multilayer coating was prepared on surface of PIP-C/SiC composites by chemical vapor deposition and slurry. The coating shows dense surface and outstanding anti-ablation ability. Compare with uncoated PIP-C/SiC, the linear and mass ablation rates of the coated PIP-C/SiC decrease by 59.5% and 50.3%, respectively, after ablation for 30 s. Large amounts of heat can be taken away by the gas generated during ablation, which is also helpful for protection for the composites.
